Allow sound files to repeat while aura is present.
Right now, when an aura is present, a sound file can be triggered. But it's only triggered once. I think it'd be useful to allow sound files to repeat at variable intervals while the aura is present - in case you miss the sound file. It'd make sounds work more like animations.
Actually on second thought, it might be possible.
I found myself wishing for this feature as well. I had just downloaded a bunch of Zelda sound effects and wanted that annoying "low health beep" noise for when I was low HP. Annoying, but it definitely gets your attention. XD
